Corduroy Road

Brief description

A road made by placing sand-covered logs perpendicular to the direction of the road over a low or swampy area.

Use / Function

  • Primary use: Allowing passage over swamps, marshes, or mud.
  • Secondary uses: Temporary military roads or logging roads.

Operating principle

  • Floating Foundation: The logs distribute the weight over a large area of soft ground, preventing sinking (similar to a raft).
  • Traction: The ribbed surface provides grip, though it is bumpy.

How to create it

  1. Clear Path: Remove brush and obstacles.
  2. Stringers (Optional): Lay two parallel logs along the edges of the path to act as rails/borders.
  3. Decking: Lay logs side-by-side perpendicular to the path. Use logs of uniform diameter if possible.
  4. Covering: Fill gaps with sand or earth to smooth the ride.

Materials needed

Variants and improvements

  • Plank Road: Using sawn planks instead of round logs (smoother).
  • Puncheon Road: Using split logs with the flat side up.
  • Wooden Pavement: Urban block paving, much more refined than corduroy roads.

Limits and risks

  • Bumpy Ride: Very uncomfortable for wagons (“corduroy” refers to the ribbed fabric).
  • Rot: Wood will eventually rot, especially if not submerged (submerged wood lasts longer).
  • Livestock Hazard: Horses can break legs in gaps between logs.
  • Road: General concept.
  • Wood: Main material.
